Abstract
The paper presents a power factor correction (PFC) method for a dual boost converter based on one cycle control. The topology features one combined rectification and PFC stage for reduced conduction losses and two separate switches for the positive and negative half line cycles operation for reduced junction heating. This topology is very suitable for higher power (1 kW or above) applications. The controller uses the one cycle control core, an integrator with reset along with a few digital and analog components, to realize PFC modulation, thus it is simple and reliable. Stability analysis and steady state design are detailed in the paper. A 1 kW PFC rectifier prototype was built and some experimental results are provided in the paper.
